4 Claims.

'Ihis invention relates to devices for ventilating rooms, and its chiefobject is to provide a device which will furnish improved ventilationand improved control thereof, and will at the same time add directly tothe illumination of the room.

Another object of the invention is to provide a device of this naturewhich will not only ventilate the room in an improved manner but bywhich also the temperature and humidity of the air in the room can beregulated in any desired manner.

A particular object of the invention is to provide a device of thischaracter which may be incorporated in an ordinary window without anystructural changes therein and which will be cheap to make and sell, yetsimple in operation and durable in service.

This application is a divisional of applicants case Serial No. 449,170filed May 2, 1930 which has matured into Patent No. 1,976,032 Oct. 9,1934.

Fig. l is a vertical section on line l-I of Fig. 3 of the device;

Fig. 2 is a vertical section on line 2-2 of Fig. 3;

Fig. 3 is a front elevation of the device; and

Fig. 4 is a horizontal section on line 4-4 of Fig. 3.

In Figs. 1 to 4, I have shown a form of the device in which the partsare arranged in such a way that the faces of the device may fit flushwith the respective faces of the window frame, as when the latter isrelatively narrow, and is particularly advantageous in cases wheresingleplane windows are used. This form is also particularlyadvantageous where a greater amount of heat radiating surface isrequired. The box is somewhat narrow transversely, but has an inlet andoutlet port system as shown at l, 8, 9, and I0, and the lighting'elements 5 preferably such as those shown are arranged preferably in themanner shown. The discharge and intake drafteffect is induced byconvection caused by elements 5', as shown, but the draft backplate andlight diffusing element 6 is so constructed and arranged that though itis corrugated and stands vertically, it is supported at the ends only,by being suitably attached to steam coils 20 located in either end ofthe casing. These coils are preferably provided with longitudinallyextending heat-radiating ns 2|, those ns which lie nearest theventilation ports being made longer than the others, as shown, in orderto positively direct the convection currents to or from the ports. 'l isa swing port, 8 another, 9 is a slide-grating, I0

another, Il a piece of frosted glass. I1, in Fig. 1, is insulationmaterial. 6 is a reecting screen, 2 is the rail of the window frame, 3the overhead.

I claim:

l. A ventilation device comprising a container having verticallyseparated openings in one side, vertically separated openings in theopposite side, means for closing the diagonally opposite pairs ofopenings alternately, incandescent means in said container intermediatesaid openings, light-diifusing means in a wall of said container betweensaid incandescent means and the room, and a member so located andsupported within the container as to form a draft stack with thelight-diffusing member and simultaneously acting as a reflector for theincandescent means.

2. A window ventilation-device, comprising a container arranged betweenthe lintel and the overhead-wall, the outer side thereof having twovertically spaced openings and closures therefor, the inner side havingtwo vertically spaced perforated shutters and register plates thereforand having translucent material between said shutters, an illuminatingelement intermediate said sides, a heating element between the inner andthe outer side, and a diffusing reflector supported in vertical positionby said heating element in such a manner as to constitute the back plateof a draft-stack for the illuminating element.

3. A window ventilation device, comprising a container arranged betweenthe lintel and the overhead-wall, the outer side thereof havingvertically spaced valve-like openings therein and closures therefor, theinner side having vertically spaced openings therein and shutterstherefor and translucent material between said shutters, a plurality ofincandescent illuminating elements arranged vertically between saidsides, and occupying the major portion of the length of the container toeach side of the longitudinal center thereof, a vertically extendingheating coil at each end oi the inside of said container, and avertically corrugated reiiecting surface connecting said coils tothereby form a draft-stack with said translucent member.

4. A window ventilation device, comprising a container arranged betweenthe lintel and the overhead-wall, the outer side thereof havingvertically spaced valve-like openings therein and closures therefor, theinner side having vertically spaced openings therein and shutterstherefor and translucent material between said shutters, a plurality ofincandescent illuminating elements arranged vertically between saidsides,

' and occupying the major portion of the length of the container to eachside of the longitudinal center thereof, a vertically extending heatingcoil at each end of the inside of said container, and a verticallycorrugated reflecting surface connecting said coils to thereby form adraft-stack with said translucent member, said coils bearing Ylongitudinal fins the fins on eachr coil nearest said openings beingmade longer horizontally than the others.
